I have tried to make the tempogram work but so far my laptop has refused to do the amount of work that is necessary for a tempogram, which is why I have settled for a novelty function for now. I haven’t spent much time on anything else, so the portfolio really hasn’t improved very much. I will probably do most of the work on the weekend before the deadline of the portfolio after all of my exams.
I haven’t been able to do much yet, but at least here is a chord-o-gram of a song by Charlie Puth who has PP.
In the pitch graph, you can see very clear boxes, especially around the 200-300 mark. These indicate novelty. The 200-300 mark is the bridge, which is why it is the clearest box (since bridges are, generally, melodically very different from the verse and chorus). You can also see some diagonal lines around the 75-200 mark, which indicate repetition. In the timbre graph however, you do not see these diagonal lines, apart from the one through the middle that indicates that we’re graphing the same song against itself. This means that there seems to be no or very little repetition within timbre. However, since the whole timbre matrix is almost completely blue, this indicates that there is very little timbral change.
A comparison of the playlists “This is Mozart” and “This is Haydn”. Mozart had absolute pitch, while Haydn did not. As you might be able to see, Haydn’s pieces have a wider range of valence for both his minor and major pieces than Mozart, especially in the high valence (positive mood) range. The compositions of both artists have a low level of energy, which is consistent with their style, but interpretations of the pieces by the orchestras performing the pieces could also have an effect. Mozart’s pieces also seem to have a wider distribution of energy in his pieces in major.
